Stablecoin settlement infrastructure comparison for platform builders not crypto native teams

Building a cross border payment product on stablecoin rails but our team is traditional fintech – coming from banks, not crypto. Every comparison I find assumes you understand wallet infrastructure and chain selection and gas optimization. I get the reasoning, but it's just not our use case. We just need faster cheaper settlement where the complexity is abstracted from us and our end users. Which providers are built for teams like us versus teams that want to manage the blockchain layer themselves?
